Oil pressure

[Shaun_E]

Looks like my head gasket has failed but there might be another problem as well. The oil pressure drops very low at idle (as low as 15 psi when hot) and at highish revs it rises to around 300psi. At first I though it might be the sensor or a poor earth but the readings are consistent and rev related so perhaps there is a more sinister problem.

I could get the HG fixed and be back on the road while I have a new engine built but I don't want to do that if there are other major problems with it.

What do these symptoms sound like they could be caused by? Is it really likely to be just the sensor? Could they even be related to HG failure?

What instrument are you using? I'm guessing SPA or Stack - as nothing else reads that high...

 

The SPA sender (for instance) shows around 300psi when it fails. I would suspect Stack to do something similar.

 

I rather suspect (but this is not backed up by experience) that 300psi would result in oil appearing virtually everywhere but the insides of your engine...

i think i have a spare Stack (VDO) sender if you want to try it

Yes it is a Stack unit. I didn't believe 300psi either but I thought I should check.

 

Mark thanks, that would be great - I'll give you a call in the week.
